can you give me a background explanation i can use to approach this problem? ### Java Inheritance ExampleConsider the three classes **Alpha**, **Beta**, and **Gamma**. What is the output of the following code that uses these classes?```javaAlpha a = new Alpha();System.out.print(a.getTwo());System.out.print(a.getTwo(2));```**Output:**```2two```### Class Definitions:- **Class Alpha (extends Gamma)** ```java public class Alpha extends Gamma { public String getTwo() { return "2"; } public String getTwo(int i) { return "two"; } } ```- **Class Beta (extends Gamma)** ```java public class Beta extends Gamma { public String getThree() { return "3"; } public String getFour() { return "four"; } } ```- **Abstract Class Gamma** ```java public abstract class Gamma { public String getOne() { return "1"; } public String getFour() { return "4"; } } ```### Explanation:- **Alpha a = new Alpha();** Creates an instance of the class `Alpha`.- **System.out.print(a.getTwo());** Calls the `getTwo()` method from the `Alpha` class, which returns the string `"2"`.- **System.out.print(a.getTwo(2));** Calls the overloaded `getTwo(int i)` method from the `Alpha` class, which returns the string `"two"`.The final output is "2two".
